Hyperfine spectroscopy of optical-cycling transitions in singly ionized thulium
Patrick Müller, Andrei Tretiakov, Amanda Younes +3
We present a spectroscopic investigation of that provides two key foundations for its use as a platform for advanced quantum applications. First, we establish…

Internal state cooling of an atom with thermal light
Amanda Younes, Randall Putnam, Paul Hamilton +1
A near-minimal instance of optical cooling is experimentally presented wherein the internal-state entropy of a single atom is reduced more than twofold by illuminating it with broa…

Primary quantum thermometry of mm-wave blackbody radiation via induced state transfer in Rydberg states of cold atoms
Noah Schlossberger, Andrew P. Rotunno, Stephen P. Eckel +14
Rydberg states of alkali atoms are highly sensitive to electromagnetic radiation in the GHz-to-THz regime because their transitions have large electric dipole moments. Consequently…
